Intraocular pressure and ocular pulse amplitude using dynamic contour tonometry and contact lens tonometry

BMC Ophthalmology, 2004
Background The new Ocular Dynamic Contour Tonometer (DCT), investigational device supplied by SMT (Swiss Microtechnology AG, Switzerland) allows simultaneous recording of intraocular pressure (IOP) and ocular pulse amplitude (OPA). It was the aim of this

Goldmann and modified Goldmann tonometry measuring intraocular pressure changes in eyes which underwent myopic laser in situ Keratomileusis and photorefractive keratectomy

BMC Ophthalmology, 2022
Purpose Compare intraocular pressure (IOP) measured by a standard Goldmann applanation tonometer prism (IOPg) and a modified correcting applanation tonometer surface Goldmann prism (IOPc) before and after laser in situ keratomileusis (LASIK) and ...

Diagnostic accuracy of the iCare rebound tonometer compared to the Perkins applanation tonometer in assessing intraocular pressure in rural patients [PDF]

, 2015
Background: Vision health is recognized as a critical unmet need in North America. The ocular morbidity associated with glaucoma results from increased intraocular pressure (IOP) and early detection is crucial for the management of glaucoma.

On the Validity of the Imbert-Fick Law: Mathematical Modelling of Eye Pressure Measurement [PDF]

, 2016
YesOphthalmologists rely on a device known as the Goldmann applanation tonometer to make intraocular pressure (IOP) measurements. It measures the force required to press a flat disc against the cornea to produce a flattened circular region of known ...

A positioning sensor for tonometric applications [PDF]

, 1992
In this paper we present a sensor, which is designed for application in a tonometer, an instrument for the measurement of intraocular pressure. The sensor measures diameter and position of a part of the eye globe that is flattened by the tonometer.

Comparative study of intraocular pressure (IP) in Bangladeshi individuals by contact and non contact technique

Bangabandhu Sheikh Mujib Medical University Journal, 2016
Background: Intraocular pressure (IOP) is one of the most important parameters in the diagnosis and treatment of glaucoma. Glaucoma has been established as the second leading cause of blindness.

Different methods for measuring intraocular pressure [PDF]

Halo 194, 2019
Tonometry is a method for measuring intraocular pressure (IOP). Goldmann applanation tonometry (GAT) represents a golden standard for measuring IOP. The measurement is conducted by measuring the force needed to straighten out a certain area of the cornea.

A large multi-ethnic genome-wide association study identifies novel genetic loci for intraocular pressure. [PDF]

, 2017
Elevated intraocular pressure (IOP) is a major risk factor for glaucoma, a leading cause of blindness. IOP heritability has been estimated to up to 67%, and to date only 11 IOP loci have been reported, accounting for 1.5% of IOP variability.
